photosynthesis would not be possible without the Carbon Cycle.


Plants and photosynthetic algae use Carbon Dioxide as one of the main reactants in the Calvin Cycle that produces organic Carbon products in photosynthesis. Carbon Dioxide is part of the Carbon Cycle. Without Carbon Dioxide photosynthesis would not occur and there would be no organic Carbon products and no life on earth.

The equation for photo synthesis is

# 6 CO_2 + 6 H_2O = 1 C_6H_12O_6 +6 H_2O#

The 6 Carbon Dioxides in the reactants are essential for the process of photosynthesis to occur. The glucose sugar molecule in the products is the basis for almost all energy reactions in living things both plants and animals.

Organic molecules are built on Carbon Chains and rings. Photosynthesis is the way inorganic Carbon enters into organic metabolic pathways, resulting in the production of muscle, skin, enzymes, nerves, DNA, and all organic compounds needed for life.

Without the Carbon Cycle photosynthesis would not be possible and living things would not presently exist.
